2015 Tbilisi Flood

თბილისის მერია 2015 წელი

The Vere is a mountain river which is unique in terms of city planning, as it flows right in the middle of the city;

The environment and conditions were radically different in the 30s when the zoo was built on the side of the river. Since

then the Vere ravine development has been carried out.

The River Vere is a natural water collector.

The River Vere - Preamble

River Areal VS Tbilisi

River Areal

Papulated area of Tbilisi

Flowing areal of the river is as large as populated area of the City of Tbilisi.

The river length - 30 Km.

30 Km

• The risk of devastating Flashflood will always be present without

proper mitigation . • The main cause of the city flooding started in mountains, due to

massive landslide. • Damage was escalated due to the constructed tunnel under the

Vake-Saburtalo road. Landslide clogged the narrow pass of the tunnel.

• The tunnel under Heroes’ Square bears a great risk also, due to being constricted on lower level of the area.

• People’s lives are in danger by unregulated massive constructions in the river bank;

• For the entire city population the safety issue is an absence of Early Warning System;

Exciting Risk Factors

Readiness for emergency situations (6) Needs of the LEPL 112

• - Organization of training for the “112” operators/dispatchers on reports management specifics during a large-scale emergency situation;

• - Operation of relevant application for transfer of the information in visual form to the "112" by civilians;

• - Creation of necessary infrastructure for automatic determination of the exact location of the report initiator;

• - Creation of an alternative Data Center in order to protect the infrastructure (fiber optic network) necessary for reception of reports in case of force majeure and insurance of such Data Center;

• - Creation of the “112” alternate center to ensure the mobilization of the required number of primary and standby shifts in case of large-scale emergencies at the same occasion, within the term of sharp increase of the repetitive messages of identical nature and its equipping with computers and relevant technique;

• - Enactment of so called "Mobile Center" in case of large-scale emergencies that means purchase of relevantly equipped bus for mobilization of primary and standby shifts where in transportation mode operators shall continuously receive reports, process and further forward the information to the relevant authorized services.

Additional Long Term Plans and Needs

For the future we need to think about public

transport plan and other necessary plans for safe livable space.

• Public transport plan implementation period is estimated for 1-5 years.

• Complex Public Transport system cost – 399 500 000 Million EUR

• 7000 Hazard buildings that need reinforcement or demolition.

Transport Systems • The June 13th flood in Tbilisi showed us that in Tbilisi the public transport system is not

adequate to the needs of Tbilisi inhabitants. • After the disaster, the problem of transportation was not only due to the damaged

infrastructure but also due to the absence or underdevelopment of the multimodal transport network.

• Two main means of public transport in the city are: buses and metro. The former needs to be developed both in quantity and quality and the latter needs expansion and overhaul repair.

• Cableway and tramway transport networks are to be added to the public transport system. • The development of the public transport will result in the decreased use of private vehicles.

Conclusion

Rapid Damaged and Needs Assessment will start on June 18 and is expected to take 2-3

weeks.

A refined presentation including a more detailed cost estimation will be circulated once the

assessment is completed.

Thank You!
